Are you using some type of RSS feed plugin?
Also, does it do it to all posts or specific posts?

Have you tried unchecking the “Automatically add paragraphs” checkbox right below where you enter the text? Perhaps this is checked and it is causing an issue with the code that you are putting in.

Software like WordPress delivers pages via the dynamic publishing method. Any software using this type of generation is inherently going to be slower when loading in comparison to pages published statically. The reason for this delay is due in large part to where your content is stored, but more importantly the retrieval of the pages. When someone visits your WordPress site, the software delivers your pages dynamically, producing them as they are called upon by a browser. So basically, the actual HTML pages that visitors to your site see are created on the fly so to speak. It is during the process of generating HTML pages which contributes to additional lag time. These dynamic pages are not stored on the server like a static page is. Another contributing factor involves making changes to your content. For example, if you go into the administrative panel of your WordPress software and add a new post, WordPress goes through a process regenerating several of your pages if not all of them. Furthermore, many folks will get motivated to change out the template. A move like that will cause every single page to be regenerated too. If you take a big website created with WordPress and every single page is being regenerated from a content change, it would not be a surprise if the server slowed to a crawl. So I would start with the hosting company and see if they have any idea what is going on. They may see a pattern and be in the process of resolving the issue.
